I have plotted this raw ECG text file from Opensignals programm on Matlab, but I want to filter it, any help? response will be appreciated.
% extract data
data = readmatrix('opensignals_98d391fd3f18_2020-05-12_viseuellentrainig', ...
'HeaderLines', 3, 'ExpectedNumVariables', 6);
% plot 6th column
plot(data(:,6))
xlabel("Zeit [ms]",'FontSize',20);
ylabel("Spannung [mV]","FontSize",20);
hold on

Hi,
Here is the link which explains how to filter high-frequency noise from ECG data. I hope it gives you an idea to work on your data.
